I To all whom it may concern:

Be it known that I, PERLEY R. GLAss, a citizen of the United States, residing at Brookline, in the county of Norfolk and State of Massachusetts, have invented certain Improvements in F rench-Binding Straightening and Cement-Applying Machines, of which the following description,

in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for use in the manufacture of boots and shoes and is herein illustrated as embodied in a ma chine used in the production of a so-called French edge.

It is customary in the manufacture of certain styles of boots and shoes to bind the edges of parts of uppers with strips of fabric. To this end such a strip is stitched to the edge of the vamp, quarter or other piece of the upper, cement is applied to the strip, and the free portion of the strip folded about the edge of the vamp or other piece and pressed down so that the cement will hold its firmly in place.

Hitherto there have customarily been three distinct steps in the'formation of the French edge after the binding has been stitched to the material. First the free portion of the binding is wiped over that portion of itself which is attached to the material until the stitches smile, that is, until they can be plainly seen. This operation is known as straightening the binding, since it leaves the free portion of the binding extending out from the edge of the material to which the binding is attached in a plane which is substantially a continuation of the plane of the display surface of the material. A machine for thus straightening the binding is shown and described in Patent No. 1,322,591, granted November 25, 1919. The second step comprises applying a coating of cement, to the margin of the material and to one side of the straightened binding strip. This has commonly been done by a hand brush. The third step is to fold the free portion of the strip over upon the material and press it into place, a machine by which this step may be accomplished being described in the patent to McIntire No. 1,278,490, of Sept. 10, 1918.

The general object of the present inventlon, ]S to provide a machine by which the first two steps, or two operations of similar nature, may be accomplished simultaneously. According to one feature of the present IIIVGIItlOII, the piece of work comprising a piece of material to which a binding or s11n1lar member has been attached is sub- Jected 1n one operation to the action of a blnding-engaging member which manipulates the binding and to an adhesive apply- 1ng mechanlsm. The illustrative machine pulls out or straightens the binding strip in substantially the same manner as that of' the application filed in the name of Mc- Intire, the adhesive material being applied by a speclally constructed feed roll to which cement is supplied. This and other features of the invention, including certain details of construction and combinations of parts will be described as embodied in an illustrative machine and pointed out in the appended claims.

eferrmg now. to the accompanying drawlngs,

The illustrative machine, except for the cement applying mechanism, is substantially like the machine of the McIntire patent. Before proceeding to a description of'the cement applying mechanism, the other parts of the machine will be briefly outlined. Fast to a rotary shaft 7 is a grooved pulley 9 which may be clutched at any time to a continuously running driving pulley 11 by depressing a treadle (not shown) connected to a treadle-rod 13. A belt 15 running around the pulley 9 over guide pulleys 10 and around a pulley 12 serves to rotate the binding engaging member 17 which is in the general form of a disk is resiliently mounted and operates to wipe or pull out the binding. The roll 19 is fast to a shaft 20 which is driven at a reduced speed from the shaft 7 by two chains 21 and 23 and suitable sprockets. The chain 21 runs around a sprocket on the shaft 7 and around a sprocket located at one end of a short horizontal shaft the bearing of which is shown at 22. At the right-hand end of this short shaft is a second sprocket, the chain 23 running around this last-named sprocket and around a sprocket fast to the right-hand end ofthe shaft 20. The feed disk 25 is mounted at the lower end of a substantially upright I shaft and is driven by belts 27 and 29 and suitable pulleys.

A bar 31 having a fork beneath a collar on the substantially upright shaft of the wiper 17: is adapted to prevent the feed disk from being lifted into contact with the wiper 17. The directions of rotation of the roll, disk and wiper are shown in Fig. 2.

Referring now to Fig. 4, the operation of the machine, as thus far described, is as follows: The work consists of a piece of sheet material 100 to which a strip of binding 200 has been attached by a line of stitches which runs parallel and close to the registering edges of the material and which is located .fabric. The operator bends one end of the fabric strip about its line of attachmentand presents the work to the machine as shown in Fig. 4. Thereafter the work is fed through the machine by the cooperation of the marginof the feed disk 25 with the cylindrical left-hand end portion of the roll, and the binding is straightened, that is, the free portion is bent over that portion of itself which is attached to the material 100. The machine, as thus far described and its mode of operation, is substantially the same as that of the McIntire patent and will not be described further in detail. It will be understood that the work, as it comes from the McIntire machine, is ready to be cemented preparatory to the folding of the binding about the edge of the material.

Hitherto it has been customary to cement the work by a hand brush or in any eventto apply the cement in a separate operation. According to the present invention the cement is applied simultaneously with the straightening of the binding. In the illustrative machine this is accomplished by a special construction of the feed roll to which cement is supplied from a reservoir. The

roll has the usual cylindrical portion which, with the feed disk 25, cooperates in feeding the work. Located inside (to the right of) this feeding portion is a stepped portion comprising a corrugated step 33 of larger diameter than the cylindrical portion and a second corrugated step 35 of less diameter than the step 33. The functions of the step 33 are to support the work for the operation of the wiper 17, and to apply cement to the under side of the margin of the material 100. The function of the step 35 is to apply cement to the under side of the straight ened strip 200 as shown in Fig. 3. Located to the right of the step 35 is a smooth hub 37 upon which the surplus cementfalls and from which it is removed by a scraper 39, adjustably held in place by a screw 41, and returned to the main body of cement in a passageway 43. The thickness of the layer of cement carried by the step 33 is regulated by a doctor 45 which is adjustable by means of a screw 47 Cement is supplied to the .roll from a reservoir 49 having a pivoted cover 51 which may be held closed by a thumb screw 53. This reservoir has an outlet in the form of the passageway 43, which has been referred to above, and terminates in the lower portion of a casing 55. This casing is generally circular in cross-section, the top being cut away to permit the roll to protrude from it. At the outer end of the easing is a closure or cap 57 having an annular rib 59 which fits closely about the end feeding portion of the roll so as to keep it free from cement. Mounted in the rib is a felt wiper 61 which keeps any cement which may get upon the feeding portion of the roll from rising into contact with the under side of the work.

It will be noted that only a comparatively thin layer of cement is permitted to be carried up to the main portion 100 of the work by the step 33 but that the step 35 is permitted to carry all that will adhere to it.

VVhen a cylindrical or substantially cylindrical roll is used not enough cement is applied to the binding. It has been found by experiment that by providing a step, such as 35, of less diameter than that of the worksupporting step 33, the binding is properly cemented. The step 35 carries at all times a thick layer of cement such that the binding need merely touch it lightly to receive the requisite amount.

Assuming that the work comprises a piece of leather 100 tothe grain side of which a strip of fabric binding 200 has been stitched, the work is fed through the machine grain side up, as has been described-above and as shown in Fig. 4, the wiper 17 operating to pull out or straighten the binding, and the roll operating to apply a coating of cement to the margin of the flesh side of the leather and to the under side of the projecting portion of the binding.
